  • Decisions that influence outcomes in the distant future

    Publication Year: 1983, Page(s):1 - 10
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1892 KB)

    An alternative solution to the classic social discount problem of making decisions that influence outcomes on future generations is presented. The methodology assumes that individuals in the current generation are the decisionmakers. The decision criterion is net willingness to pay, computed from current individuals, preferences for their own consumption and the well-being of others, including tho... View full abstract»

    A hierarchical optimization method based on the interaction prediction principle is applied to the freeway traffic control problem. The solution method is implemented on a multimicrocomputer system. Both analytical and experimental results concerning certain properties of the decentralized computation structure such as computation time, storage space, and communication requirements are presented.

    The application of dynamic programming to the modeling of decision control problems arising in research and development systems management is discussed. Probabilistic models for treating an allocation problem in the context of an antiballistic missile system are first reviewed in order to set the background for the use of fuzzy sets. Fuzzy research and development (R&D) systems are exemplified... View full abstract»

  • A method for assessing the market potential of new energy-saving technologies

    Publication Year: 1983, Page(s):30 - 37
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1771 KB)

    An approach for estimating the market potential of new energy saving technologies is presented. The approach is based on the assumption that consumers implicitly minimize total expected lifetime costs when purchasing new technology. The techniques developed allow simultaneous comparison of any number of competing technologies. An important result of this approach is that technologies can have zero... View full abstract»

  • Modeling manpower systems in two-grade organizations

    Publication Year: 1983, Page(s):38 - 47
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1447 KB)

    Organizations whose work force consists of `trainees' on the one hand and `regular employees' on the other (e.g. nontenured versus tenured faculty) are considered. A model which allows direct recruitment into both grades and assumes seniority dependent promotion policy and resignation patterns is formulated. Formulas for actual promotion and resignation densities are then derived. The model is use... View full abstract»

  • Subgraph error-correcting isomorphisms for syntactic pattern recognition

    The structure-preserved error-correcting graph isomorphism proposed by Tsai and Fu (1979) for matching patterns represented by attributed relational graphs is extended to the case of subgraphs. The resulting subgraph error-correcting isomorphism, which includes the structure-preserved error-correcting graph isomorphism as a special case, is useful for recognizing partially viewed or structurally d...

  • Generation of a pseudothesaurus for information retrieval based on cooccurrences and fuzzy set operations

    Publication Year: 1983, Page(s):62 - 70
    Cited by:  Papers (9)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1819 KB)

    A thesaurus in bibliographic information retrieval is a list of technical terms with relations among them, enabling generic retrieval of documents having different but related keywords. Since the construction of a thesaurus is resource consuming an automatic generation method of a thesaurus-like structure is needed. A set-theoretical model of an abstract thesaurus is developed which is related to ... View full abstract»

  • Incentives for controlling the performance of high technology and professional employees

    Publication Year: 1983, Page(s):70 - 74
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1526 KB)

    Many problems arise from potential incompatabilities between characteristics of high technology and professional employees and traditional organizational authority and control systems. These incompatibilities may lead to dysfunctional conflict between the role expectations of the professional and organizational requirements. Some organizations are attempting to deal with this conflict by designing... View full abstract»

  • Information-theoretical characterization of fuzzy relational databases

    Publication Year: 1983, Page(s):74 - 77

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (941 KB)

    A fuzzy relational database is a medium capable of representing information that is inherently imprecise or is the aggregation of the subjective opinions of a number of individuals. Measuring the degree of precision or lack thereof is important for two reasons. First, if the measures themselves achieve extrema when conditions match what is intuitively recognized as maximum and minimum fuzziness, t... View full abstract»

  • On two-stage parameter estimation in static system

    Publication Year: 1983, Page(s):77 - 81

    The general two-stage estimation idea is described. Maximum likelihood and maximum a posteriori probability methods for two-stage estimation are presented. The estimation algorithms for simple cases are given. The comparison of the direct and two-stage estimation is discussed. View full abstract»

    A standard thinning algorithm which consists of a matrix matching scheme used in conjunction with a connectivity measure is briefly described. Several new heuristics are introduced to obviate some of the common shortcomings of thinning algorithms when applied to handprinted data. View full abstract»

    It is shown that the `pyramid linking' method of image segmentation can be regarded as a special case of the ISODATA clustering algorithm and hence is guaranteed to converge. View full abstract»

  • A simple speckle smoothing algorithm for synthetic aperture radar images

    Publication Year: 1983, Page(s):85 - 89
    Cited by:  Papers (60)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (7157 KB)

    Speckles appearing in synthetic aperture radar (SAR) images are generated by the coherent processing of radar signals. Basically the speckles have the nature of a multiplicative noise. A simple and effective method of smoothing speckle-corrupted images by a digital computer is discussed, based on the recently developed sigma filter. The sigma filter is motivated by the sigma probability of a Gauss... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2741 KB)

    The problem of statistical pattern recognition with noisy or imprecise feature measurements is considered. An exact analytical expression is found for the probability of misclassification under this condition, for multiclass multivariate systems. The probability of error exceeds that of the ideal case for the special case of two classes, the a priori conditional probability density functions are a... View full abstract»

    An application of the theory of fuzzy sets in understanding an image is demonstrated. The task of understanding consists of three parts. A representation of image contours by their respective chains of octal codes, smoothing of the chain to remove spurious wiggles, and segmentation and assignment of degree of `arcness' to each segmented smoothed chain in order to extract their primitives for descr...

    Learning behaviours of variable-structure stochastic automata under a multiteacher environment are considered. The concepts of absolute expediency and ε-optimality in a single-teacher environment are extended by the introduction of an average weighted reward and are redefined for a multiteacher environment. As an extended form of the absolutely expedient learning algorithm, a general class ... View full abstract»
